Struct State 

pub struct State {
    pub mstk: Vec<Arc<Value>>,
    pub regs: RegStore,
    pub params: ParamStk,
}

Combined interpreter state storage

Typically, just use the Default. Fields are public to allow for presets and extraction of values, see their documentation.

regs may contain thread handles, which are not copied with Clone. To preserve thread handles in self, use:

• state.clear_vals(); instead of state = State::default();
• state.replace_vals(other); instead of state = other;

Fields

mstk: Vec<Arc<Value>>

Main stack, Arc to allow shallow copies

regs: RegStore

Registers

params: ParamStk

Parameters

Implementations

impl State

pub fn trim(&mut self)

Reallocate all fields to fit, do not discard any stored data

pub fn clear_vals(&mut self)

Clear all stored data, do not touch thread handles in self

pub fn replace_vals(&mut self, other: Self)

Replace stored data with contents of other, keep thread handles in self and discard any in other

Trait Implementations

fn clone(&self) -> State

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for State

fn default() -> State

Returns the “default value” for a type.

impl Display for State

Export to state file with standard format

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
